Albert walks 4/5 of a mile in 5/12 of an hour. Which expression can be used to calculate his unit rate in miles per hour?

Answer 1

To calculate his unit rate in miles per hour, we can use the expression:

(4/5) / (5/12) = (4/5) * (12/5) = 4 * 12 / 5 * 5 = 48 / 25

Therefore, the expression is 48/25 or 1.92 miles per hour.
